MAINE, ASSIGNOR OF ONE-HALF TO WVOLFF 8E REESSIN MACHINE FOR H EADINGSARDINE -CANS.

SPECIFICATION forming part of Letters Patent No. 301,505, dated July 8,1884-.

Application filed June 30, 1883. (N0 model.)

To all whom it may concern:

Be it known that I, GEORGE A. MARSH, of Brunswick, in the county ofCumberland and State of Maine, have invented certain .new and usefulImprovements in Machines for Heading Sardine-(Bans; and I do herebydeclare that the following is a full, clear, and exact description ofthe invention, that will enable others skilled in the art to whichjtappertains to make and use the same, reference being had to theaccompanying drawings, forming a part of this specification, in whichFigure 1 is a side elevation of the machine. Fig. ,2 is a transversesection of the lower part of the machine through the line a: y. (SeeFig. 4.) Fig. 3 is a front elevation of the lower part of the machine;Fig. 4, a top plan of the same. I

The subject of my invention is a machine for heading cans, the covers ofwhich are placed within the walls of the can and not outside them, as isthe case in the ordinary round can used for packing purposes. Themachine illustrated in the drawings is adapted for the heading ofsardine-cans. The mechanism by which the heading of such cans isaccomplished consists of a device for guiding the cover between thewalls of the can and a device for forcing the cover between the walls.The guiding device as I have embodied it in this machine consists of aframe, a, of metal, having an opening within guides or fingers c c,which are attached, as described below, to a frameof metal, a, having anopening within of the same shape as the can to be headed. This openingin the frame should have perpendicular walls I) b, and should be justsufficiently large to admit the cover of the can. Somewhat above thelower ends of the guides c c the walls of the frame cease to beperpendicular and becomehorizontal,forming a slight shoulder. Below theshoulder they maybe beveled outward and downward until they areconsiderably larger than the walls of the can. The ofiice of the beveledportion of the walls is to act in directing the guides or fingers withinthe walls of the can. Guides are preferably made of steel and attachedto the walls at their upper ends. The walls 6 I) should be grooved orslotted to receive them, and they should be attached to the walls byrivets or for forcing the cover between the walls, consisting of theplunger der 9.)

For the purpose of operating the device the mechanism next described maybe used. Upon a broad flat base is fixed the standard '5, having thehorizontal arms jj, through circular openings in which is inserted therod k, the lower end of which is rigidly attached to the pluugerf.

Pivoted to the standard 1' is the lever Z, which is bifurcated tosurround the rod is. The coil-spring a surrounds the rod be tween thearms j and the bolt 0, by which bolt the rods m m are fastened to eitherside of the rod 7c. (See Fig. 1.) The lower ends of these rods m m areconnected to the lever Z on either side of the bifurcation.

Rigidly fixed to the frame a are the rods 1' 7', one on either end. (SeeFigs. 3 and 4.) Upon these rods play the yokes p p, the rod passingthrough an opening in the yoke. (See Fig. 4.) The ends of the yokes passthrough holes in the frame a. into similar holes in the plunger f. Whenthe yoke is in this position, (see Fig. 3,) the lower edge of theplunger should be but ashort distance within the perpendicular walls I)I). (See Figs. 2and 3.) A. coilspring, t, surrounding the rod, pressesthe yoke inward. The office of the bent rod g, which is attached to therod 1', and passes through the yoke 12, is to keep the yoke from turningon the rod 0', and furnish a point of resistance for the wedges u a,which depend from the lever Z. They are connected to the f, (having theshoullever Z by the arm a, which is pivoted thereto, and may be fixed atany desired angle by the set-screw. Thelower ends of the wedges a passbetween the yoke and the rod q.

Secured to the arm j, behind the shaft or rod is, is the rod b, which ashort distance be low the arm j is bifurcated. The bifurcations passdownward between the plunger f and the frame a, through slots in thewall 12 at the back of the frame a. The depth of these slots and theposition of the bifurcations of the rod b in them should be such thattheir front surface will be in the same line with the wall I), in whichare the slots. At the points where the slots are made the guides c awill, of necessity, be omitted.

The operation of the machine is as follows: The cover is placed withinthe frame a and forced upward between the guides c 0 until the top restsagainst the plunger f. The can after being filled is placed upon thebase h of the machine, directly beneath the beveled opening of the framea. This position may be readily determined'in practice by means ofguides a a, fixed to the base at proper points. \Vhen thus placed, theinner wall of the can will be directly beneath the ends of thebifurcated rod 1) Z), the purpose of which is to prevent the can fromtipping during the operation of heading, and also to free the can fromthe guides; when headed. The lever l is then depressed, the beveledportion of the frame. passing downward around the can until the edge ofthe can meets the shoulder 6, when the lower ends of the guides a 0 willproject somewhat below and within the edge of the walls of the can, thusinsuring the pas- 1 sage of the cover within the walls, as without theguides any irregularity in or springing of the walls of the can wouldeither prevent the passage of the cover or cause a breaking down of thewalls. At this stage of the operation the wedges u u have thrown theyoke 19 from the plunger f, which, being thus released, forces the coverwithin the guides between the walls of the can. Asthe lever rises uponbeing released, the rod 1) prevents the box from following, and it isremoved from the base tobe succeeded by another. The surface of the basemay be provided on either side with grooves (see Fig. 1) graduallyincreasing in depth as they approach the sides to allow the oil which.may be forced from the can to run into a pan or other receptacle whichmay be placed beneath the base. Greater or less throw may be given tothe wedge-shaped rods to by altering the position of the arm 12. What Iclaim as my invention is- 1. In amachine for heading cans, (in which thecover is placed within the walls,) the combination of the guides orfingers for directing the cover, a device for directing the guideswithin the walls of the can, and a device for forcing the cover into thecan.

2. In a machine for heading cans, the frame a, similar in shape to thecan to he headed, and having the beveled portion (1, shoulder e,perpendicular walls I), and guides c c,'substantially as described.

3. In a machine for heading cans, the frame a, similar in shape to thecan to be headed, and having the beveled portion (1, perpendicular wallsI), and guides c c, secured thereto, substantially as described.

4. In combination with the frame a, having the beveled portion (1, theshoulder e, perpendicular walls I), and guides c 0, the plunger f,substantially as described.

5. In a machine for heading cans which receive the cover within thewalls, a device for guiding the cover, a device connected with thecover-guiding device for forcing the cover between the guides and intothe can, and

means for operating the several elements 8. In combination with theplunger f and frame a, the rod 1), substantially as described.

9. The combination of the guides c 0, attached,as described,to the innerperpendicular walls of a frame, having 'the shoulder e, and

the plunger f within the frame, for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this21st day of June, 1883.

GEORGE A. MARSH.
